| Los micoplasmas son importantes patógenos en las aves por ser responsables de cuadros respiratorios que ocasionan grandes pérdidas económicas a la industria avícola alrededor del mundo. Existen principalmente dos especies de micoplasmas como causantes de enfermedad en aves comerciales, el Mycoplasma gallisepticum(MG) y el Mycoplasma synoviae(MS). Teniendo en cuenta su importancia y la necesidad de conocer y diferenciar las diferentes especies de micoplasmas presentes en las explotaciones avícolas, se tomaron 91 muestras de hisopos traqueales de aves con síntomas respiratorios, provenientes de igual número de granjas de pollo de engorde, ponedoras comerciales y reproductoras pesadas ubicadas en los departamentos de Cundinamarca y Boyacá, Colombia, y se... |

| This is a report on the analysis of genes involved in translation of the complete genomes of Mycoplasma hyopneumoniae strain J and 7448 and Mycoplasma synoviae. In both genomes 31 ORFs encoding large ribosomal subunit proteins and 19 ORFs encoding small ribosomal subunit proteins were found. Ten ribosomal protein gene clusters encoding 42 ribosomal proteins were found in M. synoviae, while 8 clusters encoding 39 ribosomal proteins were found in both M. hyopneumoniae strains. The L33 gene of the M. hyopneumoniae strain 7448 presented two copies in different locations. The genes encoding initiation factors (IF-1, IF-2 and IF-3), elongation factors (EF-G, EF-Tu, EF-Ts and EF-P), and the genes encoding the ribosome recycling factor (frr) and one polypeptide... |

| Avian salmonellosis and mycoplasmosis are infectious diseases that, in addition of causing lack of flock uniformity, represent a hazard to human health. The objective of the present study was to evaluate the seroprevalence of mycoplasmosis and salmonellosis in commercial broilers, backyard chickens, and spent hens slaughtered at a processing plant with local health inspection in Uberlândia, MG, Brazil. A total of 210 samples were randomly collected at the time of bleeding. Samples were submitted to rapid plate serum agglutination test (RSA) for the classification of Salmonella pullorum, Salmonella gallinarum, Mycoplasma gallisepticum and Mycoplasma synoviae. In order to increase result specificity, mycoplasmosis-positive samples were submitted to... |

| There is a need for a better understanding of the epidemiology of Mycoplasma synoviae (MS) infection in broiler breeders in Brazil. Many features of the infection remain unrecognizable, because there are no clinical signs of the disease. A detailed testing was performed at each 6 to 8 weeks in three MS-free flocks introduced in farms with endemic MS infection for a follow-up epidemiological study. Every flock was monitored by polymerase chain reaction (PCR), by serum plate agglutination (SPA) and hemagglutination inhibition (HI) for serology studies, and isolation of mycoplasmas from tracheal swabs. PCR was found to be the most sensitive test, detecting early MS infection. Serology was positive in less than 50% of the sera and MS was isolated only between... |
